Value of Coronary Angiography in the Cardiac Myxoma

Abstract

Preoperative coronary angiography for cardiac myxoma not only excludes coronary artery disease but also detects the artery feeding the cardiac myxoma, which has several clinical implications. In this study, we examined cardiac myxoma cases in two tertiary hospitals using coronary angiography to identify the artery feeding the myxoma. We retrospectively reviewed 42 patients with cardiac myxoma who had undergone surgical removal between July 2008 and December 2015 in two tertiary hospitals, and recorded their baseline characteristics, echocardiographic findings, and coronary angiography. Among those 42 patients, 23 (55%) had coronary angiography before surgery and in no case was significant luminal narrowing observed. In 21 of the coronary angiograms, the artery feeding the cardiac myxoma had a vascular branch (100%), clusters of tortuous vessels with contrast medium pooling (67%), an arteriocavity fistula (33%), and a mobile feeding artery (67%). No significant relationship was found between coronary artery dominance type and the origin of the artery feeding the cardiac myxoma (P = 0.362). Identification of the artery feeding the cardiac myxoma, with a distinctive vascular appearance in coronary angiography, is important for several clinical applications such as helping to diagnose cardiac myxoma and to plan the surgical approach.

Case report: Left atrial myxoma with morphology of cavernous hemangioma supplied by the right coronary artery

“…In another retrospective study of 42 cardiac myxoma patients performed by Lee et al, 21 (50%) of the patients were discovered to have artery feeding to the myxoma. The feeding arteries in this study included right coronary artery (RCA) (57.1%), left circumflex coronary artery (LCx) (28.6%), and both (14.3%) ( 23 ). In addition, coronary angiography can reveal the distinctive morphology of the myxoma feeding artery, which can be helpful in surgical planning ( 24 ).…”

Differentiating diagnosis of atypical cardiac myxoma and thrombus by coronary computed tomography angiography imaging

“…The artery supplying the cardiac myxoma was de ned as the artery supplying blood from the coronary artery to the cardiac myxoma in CCTA multiplanar reconstruction [9]. The artery supplying the cardiac myxoma was determined by 1) a stem-like vascular branch from the coronary artery to the cardiac myxoma, 2) reticular curved vascular clusters connected to vascular branches, 3) arteriovenous stula formed in the distal segment of neovascularization or coronary left atrial stula.…”
